Pacific Western Toronto Bus Lines operates airport shuttle buses between downtown locations and Pearson Airport under the Toronto Airport Express brand. This service operates every 20 minutes during peak periods and every 30 minutes during off-peak periods.

Toronto Pearson International Airport has pick-up locations for taxis, limos, out-of-town bus and/or shuttle services, offering transportation to downtown Toronto, cities throughout Ontario, and into Detroit. Transportation can be arranged at the Transportation Information Counters located on the Arrivals Level of Terminal 3, and on the Ground Level of Terminal 1, or prearranged online through local or out-of-town service providers. Once a taxi or airport limo is arranged, proceed to the Door D1 at Terminal 1 or Post 23 at Terminal 3.

All of the major car rental companies operate out of Pearson. Some are off-airport and shuttle busses are available to their lots.
